bacterium Staphylococcus aureus can grow in media with a wide range of water activity.

In this regard it is

grow over a range of water activities between 0.90(close to freshwater) to 0.86 (close to saturated NaCl)

===================================================================

Water activity : is the fractional vapor pressure of water in a substance partitioned by the standard state halfway vapor weight of water. In the field of nourishment science, the standard state is regularly characterized as the halfway vapor weight of immaculate water at a similar temperature. Utilizing this specific definition, unadulterated refined water has a water action of precisely one. As temperature increments, aw ordinarily increments, aside from in a few items with crystalline salt or sugar.

Higher aw substances tend to bolster more microorganisms. Microscopic organisms ordinarily require no less than 0.91, and growths no less than 0.7.
